Sound guide cover

Abstract

The invention belongs to the technical field of sound boxes, and provides a sound guide cover, which comprises a main body, the main body is in an inclined half basin body shape, the bottom of the main body is provided with a sound binding device, the basin side of the main body forms a tone tuning part with a multi-stage circular arc curved surface, the sound binding device guides part of sound waves emitted by a loudspeaker to the tone tuning part, and the tone tuning part transmits part of sound waves out through diffuse reflection. The diffuse reflection sound waves and other sound waves form the sky sound with the excellent sound effect, and the sound effect requirement of the sky sound of Dolby panoramic sound is met.

Description

technical field [0001] The invention belongs to the technical field of sound boxes, and in particular relates to a sound guide cover. Background technique [0002] Dolby Atmos is a 3D surround sound technology developed by Dolby Laboratories. It breaks through the concept of 5.1-channel and 7.1-channel in the traditional sense. It can combine the video content to present dynamic sound effects; Setting up speakers, especially those with sky sound, can achieve sound field surround, show more sound details, and enhance the audience's viewing experience. [0003] In order to meet the sound effect requirements of the sky sound of Dolby Atmos, engineers set up sound-oriented accessories on the speakers, such as sound-oriented pipes. At present, most of the speakers on the market use a simple arc hollow plastic structure as the sound guide tube of the speaker to meet the directivity and sound curve requirements of the sky sound of Dolby Atmos as much as possible. The sky sound ef...

AI Technical Summary

Problems solved by technology

At present, most of the speakers on the market use a simple circular arc hollow plastic structure as the sound guide tube of the speaker to meet the directivity and sound curve requirements of Dolby Atmos' sky sound as much as possible. However, its realization The sky sound effects are not very ideal, and the speakers cannot meet the sound effect requirements of Dolby Atmos' sky sound

[0004] Therefore, there is an urgent need for a sound guide cover to solve the problem that the sky sound effects of the above-mentioned speakers are not very ideal, and the sound effect requirements of the sky sound of Dolby Atmos cannot be met.
